Since a lot of use of docker on a desktop machine has no requirement for data resiliency (web dev work where all containers can easily be wiped and rebuilt), it would be good to have a flag for "no flush" which just ignores all flush requests.

You still want e.g. incremental rebuilds and file watching for tests and all that. It's really sad to hear this hasn't been addressed in years. Development with Compose on Linux is such a pleasure.

You can still have all that - flushing behaviour only affects things if the host machine suddenly kernel panics or loses power. For a laptop with battery backup that's probably a once a year occasion. In that case, I'd be happy to wait a few minutes for some docker stuff to be rebuilt.

You can't, when you're on a Mac and your code is bind-mounted into the container. This is the most comfortable method of development for me, and works perfectly on Linux. https://github.com/docker/for-mac/issues/3677
